Dictionaries that work offline

Each dictionary downloads once and lives in your browser. Flip the switch: lookups never needed the internet.

Espera, ¿oíste eso?Wait, did you hear that?

  • Trust a machine to guess what was said.

Questions

Good questions.

The short answers, with nothing in small print.

Which sites does it work on?

Netflix, YouTube, Disney+, Prime Video, and HBO Max. On YouTube it works on regular recorded videos, including playlists, theater mode, and fullscreen; Shorts, live streams, and embedded players aren't supported. Disney+, Prime Video, and HBO Max support is new, so it's labeled early access.

Do I need an account?

No. Install the extension, choose your two languages, and press play. There's nothing to sign up for.

Does it really work offline?

Word lookups do. Each dictionary downloads once and then lives in your browser, so looking up a word never needs the internet. Streaming the show itself still does, of course.

Does it use AI or machine translation?

No. Both subtitle lines are the streaming service's own tracks, and definitions come from open dictionaries built from Wiktionary. Nothing is generated or guessed.

What if a show has no subtitles in my translation language?

You still get the subtitles in the language you're learning, one-click lookups, the transcript, and line replay. Only the second line is missing.

What about YouTube's automatic captions?

They work, and they're clearly labeled as automatic, because speech recognition sometimes mishears.

Can I change how the subtitles look?

Yes. Each language has its own color and size, from 14 to 48 px, with eight presets or any hex color. Changes show up in the player right away.

How does pronunciation work?

Listen uses the voices already installed on your computer, so nothing is sent anywhere. If a language has no voice on your device, the button simply isn't available for it.

Your next episode
is your next lesson.

Keep watching what you love, and understand a little more of every episode.
